Forum OpenACS Development: Re: Can we use namespace variables to avoid upvar?
Therefore, if someone implements namespace cleanup in a manner which is clear, efficient, and optional, I can't imagine why the AOLserver maintainers wouldn't accept it. AFAIK the problem is that no one has attempted to implement it.
On the other hand, What Jon G. and others would like here, is some sort of removal of left over global and namespace variables from the thread when each connection request completes its processing.
It wouldn't hurt to ask Zoran about it though, he's likely to have some ideas.
